Now, you are given that and that . What is the ratio of those two? What is the ratio of to ?(b) How does the height of the bore compare with its initial height when the velocity of the tip is reduced to one quarter of its initial velocity?
The height is reduced to [____] of the initial height.
The velocity of the first is [____] times that of the other. Really the same as (a) isn't it? and . What is the ratio of to ?(c) If the tip of one bore surging up a dry river bed is four times the height of another, how do their velocities compare? (Round your answer to two decimal places.)
(I'm not even sure what to do here. How do I use the homogeneity of power functions to help me find the answers when no values are given?)
